Other Parts Discussed in Thread: TPS61089
Figure1
Vin=3.8V,Vout=4v,5 resistance load
Figure 2
Figure 1 is the start-up waveform of TPS61023 which I tested, and figure 2 is the start-up waveform of the chip manual. There is a big difference after comparing the two. What is the reason?
Figure 3
Vin=4V,Vout=4v,12 resistance load
